The property has a Mitel Messenger card in a sx 200 most of the ext are 4 digits but some are 3. the ones that are 3 are programmed as 4 digit mbx with 3 digit ext. All have worked for yrs all of a sudden 1 of them the message light will not work so I try another phone still nothing. Put the phone that I was using on another ext it works. So I deleted the mbx and ext reprogrammed still does it. All others still working. So I change the mbx from 1223 to 4223 still nothing. But if you hit the message button in all circumstances it takes you to your mbx and says you have messages. So I changed the mbx and ext to 5223 and all works. So it seems to be an issue with just that mbx and ext with 3 digit seeing as all other 3 digit exts are working. Anyone ever see anything like this?


Thanks in Advance
